About the DNS resolve

[chuanpeng.wang]

I have two nameservers in /etc/resolv.conf in HPUX server:
nameserver1
nameserver2

As I known, if the nameserver1 is not available, the HPUX will try the nameserver2.
My question:
If the nameserver1 is available, but refuse resolve, does the HPUX try the nameserver2?

Hi,

Name servers are queried in the order they appear in the file primary, secondary

From the 'man 4 resolver' man page:

"The algorithm used is: Try a name server; if the query times out, try the next and continue until all name servers have been tried, then repeat trying all the name servers until a maximum number of retries have been made."

So, if nameserver1 is available and answering queries, but is unable to resolve a request, then NO it will NOT go to nameserver2.
